Navigating the New Era of Learning: Top Generative AI Books for Programmers

Hello, we’re Computer Science Professors Dr. Leo Porter and Dr. Daniel Zingaro. We’ve dedicated our careers to helping students succeed in programming and computer science courses. There are approaches we know are effective in teaching novices, such as learning from worked-out examples and using real-world problems that resonate with students. When we’re reading a book, we’re always thinking: will this book help people learn? Does it use what we know about learning to serve as an effective teaching aid? Can we use this with our students? Can we for once stop analyzing the book and just read for fun? (The answer to that last question is, unfortunately, ‘no,’ 😀 We can’t help it!)

With massive changes happening due to generative AI tools like ChatGPT and GitHub Copilot, you won’t be surprised that there’s a swarm of new books that use generative AI to teach programming to beginners or to enhance what programmers can do.

In this article, we wanted to cover our top four generative AI books that are being published by Manning Publications.

Introduction to Generative AI
Introduction to Generative AI: An ethical, societal, and legal overview Numa Dhamani and Maggie Engler

We know, we know: you just want to use generative AI to supercharge your programming productivity. We want that, too! But we’re at the dawn of a programming revolution here, and we strongly encourage you to take the time to understand the ethical and legal concerns wrought by generative AI. 

What happens when generative AI models ingest objectionable speech or personal data? Why are these models apt to produce hallucinations, and why should we care? Why is it so difficult to address bias in machine learning? What is the critical role that human feedback plays in LLM training, and what are the associated costs to humans? Does generative AI’s use of copyrighted work fall under fair use?

As informed end-users of generative AI, it’s up to us to answer these questions–to understand what data we might be using, how that data was produced, and the societal and ethical impacts of these tools. This book helps us toward those answers.

We appreciate that many claims in the book are supported with references that the reader can check for additional details. We also benefited from numerous powerful examples throughout the book, such as racial bias in movie sentiment scores, a ChatGPT data breach, and a famous virtual influencer.

We’d also like to emphasize that while the focus of the book is on the responsible use of generative AI, there is also a non-mathematical overview coverage of how generative AI tools work, which we suspect will be of interest to many readers. For example, you’ll learn more about many concepts you’ve probably heard about in passing, such as foundation models, fine-tuning, emergent properties of LLMs, zero-shot and few-shot learning, and chain-of-thought prompting.

Finally, we applaud the balanced discussion of the pros and cons of synthetic media, the ways that LLMs are and will be misused, the ways that professionals are using LLMs and–of course!–the coverage of the impacts on education.

Dhamani and Engler’s Introduction to Generative AI is a must-read foundational guide not only to understand how generative AI works but also to understand its broader societal implications.

Learn AI-Assisted Python Programming
Learn AI-Assisted Python Programming: With GitHub Copilot and ChatGPT Leo Porter and Daniel Zingaro

The two of us (Daniel Zingaro and Leo Porter) wrote this book because we believe that the way new programmers learn to program has changed dramatically now that generative AI is here. We’ve both taught thousands of students to program over the years and a lot of our time needed to revolve around teaching syntax, which is the ways that words and symbols are put together to create programs that run. But generative AI handles syntax extremely well (which is a good thing, because many learners find syntax boring and frustrating). So, in writing this book, our guiding question was: what are the main skills that new programmers need to learn now?

In this book, written for absolute beginners, you’ll be writing programs that work from day one, in contrast to the before times when you would have had to learn lots of syntax first. You’ll learn how to test code that comes from the generative AI to check whether it is correct, break down large problems into smaller bits that the AI can better solve, and use a debugger to trace your code very carefully to see what it’s doing. Oh, and you’ll be learning Python along the way, too, in case you need that for your resume 🙂

Why would you buy and read a book with ‘obsolete’ in the title? What the author is getting at with this irreverent title is that generative AI is moving so quickly that everything written about it will be obsolete quickly. We may as well understand the foundations of effectively interacting with these tools, which is what this book focuses on.

The book starts by explaining the background concepts you need to know when working with generative AI tools. What’s a token? What are the differences between all of those GPT models? What the heck is temperature and Top P?

You need Python experience to read this one. This isn’t a programming book, though. It’s a “let’s see what we can do with generative AI!” book. You’ll generate fiction (not very good fiction… yet?), generate book cover images, convert slides to videos, and quickly obtain summaries of boring meetings and long PDF documents. The book tours many powerful generative AI tools that you may not have been aware of–it goes way beyond what the general public is doing with ChatGPT.

The key takeaway of the book is that the best results come from pairing your domain knowledge with the explosion of content you can create with generative AI.

AI-Powered Developer: Build great software with ChatGPT and Copilot Nathan B. Crocker

OK — so you’re already a Python developer and you want to start using LLMs to rocket your productivity. How? By reading Crocker’s new book 😀

This book shows you how to use GitHub Copilot, ChatGPT, and Amazon CodeWhisperer (and when to use each). It assumes that you already know Python, and we further suggest that familiarity with building APIs in Python would be a plus.

Through its chapters, you’ll build an Information Technology Asset Management (ITAM) system, using generative AI for each step… from designing the system to writing the code, generating data, testing and managing the deployment, and helping with security. (Yes: generative AI is useful way beyond writing code for you!)

The pro of writing the book as one comprehensive example is that you see how a complete application is built and deployed with generative AI help. The cons are that it makes it difficult to jump around the book and that if you are not motivated by the chosen example then the book itself may not be as motivating as a collection of smaller examples. We need books of both types!

For us, the material on system design is of particular interest, because in our time working with generative AI, we have done the high-level design and left the low-level code to the AI. Crocker’s book shows that experienced programmers can indeed push generative AI into the design realm as well, including proposing designs, creating class diagrams for designs, and comparing and contrasting potential designs.

Whether you want to understand generative AI at a societal level, to learn programming from scratch “the new way,” to add generative AI to your programming toolbox, or to be inspired to use generative AI to … generate (sorry!) content, we’re confident that you’ll find value in one or more of these books.

Manning Publications is a premier publisher of technical books on computer and software development topics for both experienced developers and new learners alike.

Manning prides itself on being independently owned and operated, and for paving the way for innovative initiatives, such as early access book content and protection-free PDF formats that are now industry standard.

Passwords are DEAD, Let’s meet Passkeys and our new State of Software Supply Chain Security Survey 

Let’s get real. It’s a pain generating unique long alpha-numeric passwords and 2-factor authentications for every web or app service we use today, often ending up using the same old password (we can remember) across services and skipping 2fas if not enforced. Even if you use a password manager to generate and auto-fill your state-of-the-art strong passwords, you’re still vulnerable to attacks like Phishing, where a website looks identical to the one you are trying to access, although in reality it is a fraudulent copy -trying to use and steal your passwords as soon as they’re entered. 

Using a 2-factor authentication is handy in this situation. Still, it involves either SMS-based OTPs or authenticator apps like Authy or Google Authenticator for TOTPs, requiring cellular connectivity or installation of additional apps. Not to mention, if you lose your password manager, it will be a nightmare. 

Enter Passkey 

Passkey is a new passwordless authentication, standard by the FIDO alliance that aims to replace passwords and 2FAs, providing a faster, easier, and more secure authentication process.


Passkeys work on public-key architecture, generating public and private keys for each web or app service you use. The public key is saved on the web/mobile service server you intend to use, and the private key is kept securely on your local device, e.g. your Smartphone. Every modern smartphone processor today has a Secure Element which will generate and save these passkeys, which means not even  you can  read or directly access your private key. 

Whenever you want to authenticate on a service,- a signature generated from your saved public key will be sent to your device, and you can authenticate this signature using your private key + Biometric Authentication, e.g. your device PIN, fingerprint or Face ID. Once the signature from the public key and private key matches, you’ll be successfully logged in, meaning you don’t have to enter any password or OTPs, saving you from creeping eyes while entering your passwords in the coffee shops. The Private key never leaves your device, and you don’t need to remember everything, + it’s Phishing proof since Phishing sites won’t have your public key anyway 😉 

So, to actually hack you, the hacker will require your device + your fingerprints/FaceID, and I don’t wanna imagine that scenario anyway.

Passkey in Action

Every service you wish to use will generate a unique passkey that can be synced across all your devices using the ecosystem cloud sync, e.g. iCloud or password manager provided by your browser. You can also share your passkeys with devices and people you want. Hardware keys like Yubikeys can also be used to generate and save passkeys. If you’re on a desktop, you can still use your mobile device for passkey authentication using QR codes generated by the services while trying to log in. The QR code can then be scanned by your phone and finished with the passkey authentication. 

For businesses, it saves cost on OTP services you provide for your users, and it’s pretty easy to add support for passkeys in your web or mobile applications using already existing authentication APIs offered for all major platforms – iOS, Android, Chrome, etc.

To start with Passkeys, look at the services already supporting it at https://www.passkeys.io/who-supports-passkeys and join the Passwordless train.

Innovations in App Development for Enhanced Data Protection

We live in an era when everything is digital, where data is the currency of the digital realm, and the need for robust data protection has never been more critical. With the rapid growth of mobile applications, ensuring the security of user data has become a top priority for businesses. This is especially true for industries like transportation, where the development of apps like taxi app has revolutionized the way, we commute.

We will explore some of the latest innovations in app development that are geared towards enhancing data protection in applications like taxi apps. These innovations not only safeguard sensitive information but also inspire user confidence, ultimately leading to the success of the app and the business behind it.

1. End-to-End Encryption

One of the fundamental innovations in data protection for apps is the implementation of end-to-end encryption. This technology ensures that data transmitted between the user’s device and the app’s servers remains secure and private. In the context of a taxi booking app, this means that personal information, location data, and payment details are all encrypted, making it nearly impossible for hackers to intercept or decipher.

2. Biometric Authentication

With the rise of fingerprint and facial recognition technology, app developers have integrated biometric authentication as an additional layer of security. Users can now access their taxi booking app using their unique biometric features, adding a robust shield against unauthorized access. This not only provides enhanced data protection but also enhances the overall user experience.

3. Multi-Factor Authentication (MFA)

Multi-factor authentication is another innovation that has gained prominence in recent years. Apps like the develop taxi app can implement MFA to require users to provide multiple forms of verification before granting access. This extra step significantly reduces the risk of unauthorized access and data breaches.

4. Secure Cloud Storage

Cloud technology is an integral part of modern app development. To ensure data protection, app developers are now using secure cloud storage solutions that prioritize encryption and regular security audits. This ensures that user data stored in the cloud remains safe from data breaches or leaks.

5. Regular Security Updates

The landscape of cybersecurity is constantly evolving, with new threats emerging regularly. To counter these threats, app developers must provide regular security updates to their users. These updates patch vulnerabilities and keep the app’s security measures up-to-date, offering ongoing protection to users.

6. Privacy-Centric Design

Innovative app development goes beyond just implementing security features; it also involves a privacy-centric design approach. Developers are now designing apps with data minimization in mind, ensuring that only essential user data is collected and stored. This not only reduces the risk of data breaches but also enhances user trust.

7. Machine Learning and AI

Machine learning and artificial intelligence are being leveraged to identify and respond to security threats in real time. For taxi booking apps, this can mean detecting fraudulent transactions or suspicious user behaviour and taking immediate action to protect user data and finances.

8. Blockchain Technology

Blockchain, known primarily for its role in cryptocurrencies, is finding its way into app development for enhanced data protection. It provides a decentralized and tamper-proof ledger, making it an excellent choice for securing transactions and sensitive data within apps.

9. User Education

Innovations in data protection also include educating users about best practices for safeguarding their data. Taxi booking apps can incorporate in-app tutorials and tips to help users understand how to protect their information and make informed choices.

10. Regulatory Compliance

With the increasing focus on data privacy regulations like GDPR and CCPA, app developers must ensure their apps comply with these standards. This not only protects user data but also shields the business from legal consequences.

Conclusion

In terms of apps, like the establishing taxi apps, continue to evolve with a strong emphasis on data protection. These innovations not only keep user data safe but also contribute to user trust and the overall success of the app. As the digital landscape continues to change, staying up-to-date with these innovations is crucial for any app developer aiming to provide a secure and reliable experience for their users.

From Novice to Notable: Essential Steps to Shine in Web Development

So, you want to be a web developer. But not just any web developer – you want to make a name for yourself. Work as a freelancer for the biggest and best companies, developing the coolest products, or landing a job at the most renowned companies in the world.

If that sounds like what’s on your vision board, you’re most likely not looking for yet another article with generic advice on becoming a web developer – you want to learn how to become a great one. 

We can’t promise you it will be an easy road, nor will it be a short one, but in this article, we provide you with a map that leads you along the essential milestones you need to pass. We’re not here to just scratch the surface, we’re going to dive deep. 

Foundations first: it’s not just about the code

Yes, when becoming a web developer, mastering HTML, CSS, and JavaScript is as crucial as learning the alphabet when you first go to school. But web development is much more than that and stretches far beyond programming languages.

You will need to be or become a great problem solver, understand algorithms, be comfortable chiming in on User Experience necessities or UI design and have a knack for system design principles. 

So when you embark on this journey, don’t just limit yourself to programming courses – keep it fun for yourself by branching out into relevant fields. The more you understand the bigger picture, the better you’ll get at working on the details.

Specialize, but diversify

We know that sounds as vague as a direction as ‘take a sharp left to the right’, but it’s where you make a difference. But there are 24.3 million active developers in the world and that number is expected to grow to more than double in the next decade to about 45 million, in 2030.

You can choose to dive deep into React, become the best at Node.js or turn into the go-to guru for GraphQL, based on your interests and talents. Yet as you root down in your specialization, it’s important to branch out into more diverse fields. 

We don’t mean knowing a little bit of everything but learning about adjacent technologies or emerging trends that are tightly knit with your specialization, like cybersecurity from a web development perspective. This makes your knowledge much more practical and easily applicable in projects and new roles, and you’ll easily blend into bigger teams.

Passion, meeting demand

When determining what your root specialization will be, keep an eye on what the demand for that is like. That doesn’t mean that you should necessarily follow the route to whatever is most in demand. You can still choose something that is less sought after, as long as you have a clear idea of where you want to end up and what you bring to the table. Be ambitious and be realistic in equal measures. 

Don’t just check what the current or projected demand for a specific type of web developer is, but also look at past data to understand what is happening. If possible, talk to industry experts to find out the reason behind it all – this will help you gauge what is risky and what is worth pursuing. 

Hands-on projects: create your own ticket to real-world experience

It’s a paradox as old as time: you need experience to get started, but you need to get started to gain experience. Don’t sit back and mope about this: start with beginner projects to get hands-on experience that you can show off.

Create a simple ecommerce website or a website for a business. Experiment with these. Try to recreate more difficult web projects to hone your skills and learn to see how the experts come to certain conclusions and setups. You don’t need to contact them to turn them into your mentors. 

Start up side projects for yourself, even if it’s just a website, on which you try to record your progress as a web developer. Over time, these side projects, even if they’re just fictional, will fill up your portfolio. Showing off an unpaid passion project or unofficial work is always better than having to say you don’t have anything yet. 

You can even seek out collaborations with other soon-to-be professionals in related fields to really polish up your projects. Think designers, copywriters, photographers or anyone else who works in fields that web developers will eventually have to work with. 

Networking: it’s about how you work together

Like many industries, web development is one of those where it does matter who you know. You don’t have to sign up for every in-person event (although, if that’s your jam, go for it!), but you can start online. Start leveraging the communities that have formed on social media platforms. 

Get familiar with GitHub and dive into the world of Dev.to. Find Reddit threads and communities where you can connect with like-minded people or people you can learn from. X and LinkedIn are also great places to connect with people and stay on top of trends.

In those groups, you’ll likely see events that are organized, like coding boot camps, hackathons, or even local coding groups. It might feel awkward at first, or strange (or it doesn’t, if you’re an extrovert), but try to ease yourself into these events. Not just for the connections you’ll build: you will also learn how to collaborate and put your skills to work in new ways. 

Digital presence: your portfolio is part of your portfolio

As a web developer, you can hardly expect that you can get away with just a resume. You are building products, and those just don’t come to life as a simple link in a PDF. 

It’s time to start building your personal portfolio website – which, in a sense, is part of your portfolio. On this website, you can share projects you’ve worked on. You can build more authority in your field by writing (technical) blogs. If you’ve contributed to any open-source projects, this is also the place to show that off. 

Leveraging AI in web development journey: job searching made easier

You can’t ignore AI in web development nor in the journey to becoming a web developer or landing a job in the field. AI-powered tools like the best AI resume builders will be your personal assistant, laying the groundwork for you. 

A common misconception is that these AI resume builders will only help you create all-size-fits-one, generic resumes. That’s only when they’re used wrong. If you let AI create the foundation you need for your resume, you can then perfect it even further with personal touches and creativity. If you start from scratch, by the time you get to this stage, you’re probably too tired or frustrated to really make your resume pop. 

Continuous learning: plan on how you’ll stay relevant

Web developers all face the same challenge: their profession and industry are quickly evolving. New frameworks, tools and trends change the landscape daily, and you’re going to have to create a structure for yourself that helps you keep up with it all.

Set learning goals for yourself: attend one webinar a week, write one blog a month on a new trend, or go to industry conferences with like-minded friends. The key here is to have a plan in place for how you plan to educate yourself – don’t just let it be something you do when you’ve got some time to spare. 

You can also squeeze in some learning on the go with online courses or podcasts, or by following big names in web development on social media. We’ve got a great knowledge base ready for you to dive into.

So, what’s your next step?

It’s important to understand that there is no surefire framework to follow that guarantees success. It’s a continuous process that might feel like you’re going back and forth, doing various things at once.

But to avoid it becoming so chaotic that you’d rather just give up, start by writing out a plan for the next twelve months. This doesn’t have to be a strict timetable but a flexible guideline that will help you stay on track.

Your first month could be dedicated to intensive learning and bruising up on your foundational skills. Plan on your first project for a few weeks from now. Make sure you create a system that helps you document your progress, learnings, and challenges – as tangible proof of your progress.

Start networking early. You can already dive into groups on LinkedIn and find threads for newbies or like-minded people on Reddit. 

Plan the things that excite you most as well, like building your own website, to keep you excited.

Your roadmap isn’t set in stone, but a living document. Keep it somewhere you can access it easily and check in often. Good luck!

Ionic app development: Pros and Cons 

Today’s time is filled with revolutionary technologies developed to simplify lives and business operations. Mobile app development is one such game-changer technology. Apps developed for mobile devices facilitate ease in different aspects of human life and simultaneously help organizations/companies achieve their business goals.   

Mobile app development is a process that leverages various powerful tools and technologies to offer utility to users and revenue to businesses. These tools include frameworks, libraries, etc. One such framework is Ionic. It is a platform that helps developers build cross-platform apps in no time.   

In this blog, we will talk about Ionic mobile app development, followed by its pros and cons.   

This would help businesses make the right choice when it comes to choosing the most suitable tools and technologies for their ambitious mobile app development projects.    

What is Ionic Mobile App development?  

The ionic framework was created in 2013 by Drifty Co. and it is not new to mobile app development. This framework allows developers to develop high-quality hybrid mobile applications using web technologies such as HTML, CSS, and JavaScript.  

Unlike React, Angular, and Vue, the Ionic framework is easy to learn for developers. Developing Ionic apps is based on the following principle – Write code once and run it everywhere. This allows developers to create apps that work across multiple platforms and devices.  

Since this framework has been developed, over 5 million apps have been created using it. Such cross-platform apps look like native apps and offer all the functionalities that are available to native iOS and Android apps.  

Is Ionic good for mobile development?  

Ionic is known to be a stable framework that builds cross-platform apps in no time, using a single code base and ready-to-use components. Furthermore, this platform gives access to native functionalities for every device and mobile OS type.   

The mobile-first approach of this framework, leveraging the power of HTML, CSS, and JS helps in the development of premium quality desktop, Android, iOS, and PWAs.  

Let’s look at some of the benefits that businesses get from Ionic mobile app development.   

Pros of Ionic Mobile app development  

Here are some advantages of Ionic Mobile app development:  

  1. Single codebase for multiple platforms  

With the Ionic framework, you can build cross-platform apps using a single codebase. Such functionality allows the developers to save their time and effort and lets them work on other aspects of the development process.  

If you are familiar with web technologies, you can still create native apps without the need for native developers. Hence, a single codebase feature helps companies to reduce their cost of development along with faster time-to-market applications.  

  1. Offers a rich library of UI components  

With its rich library of building blocks known as components, it allows developers to create interactive applications that give a native-like look and feel.   

Having such ready-to-go components as buttons, tabs, and other navigation elements, developers can focus more on the features of an app rather than creating UI components from scratch.  

  1. Open source  

While other app development frameworks are available for free, the ionic mobile app development framework is open source meaning it’s available for free.  

Moreover, Ionic has a big community wherein developers and programmers are always active on social media and the majority of them used to hang out in Slack channels.  

  1. Wide range of Integration capabilities  

The Ionic framework provides an array of integration capabilities, and you can integrate it with various tools that are mentioned on the Ionic website. Integration with such tools and technologies provides easy access to security, payment systems, and testing tools.  

In addition, developers can add a variety of features and functionalities to mobile apps with no more hassle.  

  1. Faster time to market  

With ready-to-go UI components and a single codebase, developers can create faster apps within a shorter span resulting in faster time to market.   

Despite all the benefits, the Ionic framework has some shortcomings that businesses need to consider before beginning the development process.   

Cons of Ionic Mobile app development  

The following are some disadvantages of Ionic mobile app development:   

  1. Performance issues  

Ionic framework develops hybrid apps, which means that all other platforms use a single codebase. As a result, the performance is slow and compromised in comparison to native apps.   

Furthermore, Ionic lacks suitability for the performance of heavy apps. Since it renders its graphic elements using a browser, the images shown on the screen are delayed. This happens due to the multiple steps involved in the process. The more input added in between, the longer the loading time, apart from the Cordova callbacks and CSS animations loading.  

  1. Plugin-related issues  

Apps developed with Ionic access native functionalities using the ready-made plugins offered at the time of development. With these plugins, finding a package to add the required functionality is easier. However, not every time could a developer find a suitable plugin or module. In such cases, a customized plugin must be developed for specific features.   

The issue that arises here is that the capabilities of Ionic are limited in this respect. It cannot implement native plugins without transforming them into JavaScript. It allows developers to go fully web, but the use of even a bit of native code is not possible.  

  1. No hot reloading  

The feature of hot reloading allows developers to add and apply changes without having to reload the entire app. The absence of this feature in the Ionic framework means that whenever changes are applied, the entire app restarts through a live reloading feature. This may slow down the entire development process, causing further delays in the project, and is not convenient to developers.   

  1. Not for every app  

Ionic mobile app development is not suitable for the development of some types of apps such as gaming apps. The apps that offer the 3D gaming experience cannot be developed using this framework. Since only CSS is used, the graphic quality and performance are often sub-standard.   

And when it comes to banking or finance-related apps or information-carrying apps, security is an issue. There is no built-in code uglification provided by Ionic CLI since its 4th version. Now, what is that? Code uglification is a common technique that raises code difficulty, making it difficult to read by hackers. Using Angular CLI or older versions of Ionic also does not make the situation any better. Developers need to uglify the code on their own in that case too.  

Conclusion  

Thus, like every other framework, Ionic has its pros and cons. Every business should weigh them and make a decision, accordingly, based on its needs.   

Ionic is the most suitable framework for developing creative hybrid apps with great UIs in less time. With limited features and drawbacks, it is not so suitable to create high-functioning native apps. Businesses should bear this in mind while making a choice.   

Despite all the shortcomings, Ionic is a powerful technology that deserves a fair chance to prove itself.   

Editor Notes: If you want to learn more about Cross-platform web/app development and Ionic framework, we have a full Podcast Episode dedicated on it with founder of Ionic Academy –  Simon Grimm.

Empowering Developers: Harnessing Headless Ecommerce for Omnichannel Strategy

In an era where digital commerce is king and consumers demand more seamless and personalized shopping experiences than ever before, traditional ecommerce approaches have reached their limits. 

Enter the game-changer: “Headless Ecommerce,” a concept revolutionizing the way we engage with customers across multiple digital channels.

In this digital age, where consumers seamlessly transition between websites, mobile apps, social media, and even voice-activated devices to make their purchases, the need for a unified and flexible approach to online retail has never been more critical. 

This is precisely where headless ecommerce steps into the spotlight, empowering businesses to craft tailored, immersive, and high-performance experiences for their customers.

In this article, we’ll explore the concept of Headless Ecommerce, explaining why traditional content management systems no longer meet the omnichannel challenge. 

We’ll delve into the advantages, trends, as well as challenges faced by retailers as they navigate the path to omnichannel excellence.

So, fasten your seatbelts as we embark on a journey to discover the power of “Empowering Developers: Harnessing Headless Ecommerce for Omnichannel Strategy.” 

Explore the transformational capabilities of headless commerce, and how it empowers businesses to meet the demands of an ever-evolving digital retail ecosystem.

Definition of Headless Ecommerce

Headless ecommerce refers to a modern approach to online retail where the front-end (the user interface) and back-end (the content management and commerce engine) of an ecommerce platform are decoupled or “headless” from each other. 

This decoupling allows for greater flexibility and customization in delivering content and shopping experiences across various digital channels. 

Unlike traditional content management systems (CMS), which tightly integrate the front-end and back-end, headless ecommerce empowers retailers to deliver consistent and engaging experiences across web, mobile apps, social media, chatbots, and more.

Why Traditional CMS is Not Suitable for Omnichannel Strategy?

Traditional CMS platforms are designed primarily for website management, which makes them ill-suited for the complexities of omnichannel retail. 

Here are a few reasons why traditional CMS falls short in supporting an effective omnichannel strategy:

Limited Flexibility

Traditional CMS systems often provide limited control over the presentation layer, making it difficult to create unique and tailored experiences for each channel. 

With headless commerce, developers have the freedom to design and build user interfaces that are optimized for each channel.

Inefficient Performance

Traditional CMS systems can struggle with the demands of handling multiple channels, resulting in slower page load times and a subpar user experience. 

Headless ecommerce, on the other hand, optimizes the delivery of content, resulting in faster page load times, reduced bounce rates, and improved search engine rankings.

Integration Challenges

Integrating a traditional CMS with multiple sales channels and backend systems can be complex, time-consuming, and costly. 

Headless ecommerce platforms are designed with robust APIs that make it easier to integrate with various sales channels, enabling a unified inventory management and order fulfillment process.

Advantages of Headless Ecommerce in Omnichannel Strategy

Now that we understand the limitations of traditional CMS, let’s delve into the advantages of harnessing headless ecommerce for your omnichannel strategy:

Flexibility and Customization

  • Tailored User Experiences

With headless commerce, retailers can provide tailored user experiences for each channel. Whether a customer is shopping on a website, mobile app, or social media platform, the experience can be optimized to suit the specific preferences and behaviors of users on that channel.

  • Channel-Specific Content

Headless ecommerce allows retailers to create and deliver channel-specific content, promotions, and product information. 

This means you can cater to the unique characteristics of each channel, ensuring that your messaging resonates effectively.

Scalability and Performance

  • Handling High Traffic Loads

Headless ecommerce architectures are built to handle high volumes of traffic and transactions. This ensures that your system remains responsive even during peak shopping seasons or flash sales, preventing potential revenue loss due to slow or unavailable websites.

  • Improved Page Load Time

By separating the front-end from the back-end, headless ecommerce can optimize the delivery of content. This results in faster page load times, enhancing the user experience and improving your site’s SEO ranking.

Integration Capabilities

  • Integrating with Multiple Sales Channels

Headless ecommerce platforms are designed with robust APIs that simplify the integration with various sales channels, including marketplaces, social media, and third-party applications.

This integration allows for a unified inventory management and order fulfillment process, reducing operational complexity.

  • Data Synchronization

Data synchronization across channels is streamlined with headless ecommerce. This ensures that product information, inventory levels, and customer data are consistent and up to date, enhancing the overall customer experience.

Empowering Developers for Success

The Power of Cross-Training in Programming Languages

As the digital landscape evolves, the hierarchy of top developer roles adopts a pyramid design, with programmers holding the lion’s share at 43.2%. The revolutionary wave of digital transformation and the advent of groundbreaking technologies have substantially increased the appetite for developer roles. These innovative tech breakthroughs are fuelling the need for diverse and adaptable developer capabilities. In this structure, students studying Computer and Data Science represent 15.1%, followed by team leads and architects who account for 9.64% and 9.15% respectively. Capping the pyramid are C-level notches, including IT Managers, forming 8.38% of the total. In response to the rapid influx of emerging technologies, tech professionals are urged to master a range of in-demand skills, thus ensuring an edge in this mutable tech arena. This not only augments their adaptability and earnings potential but also paves the way for ongoing career progression. Additionally, tech professionals looking to stay ahead of the curve could consider ‘cross-training’ – the practice of mastering multiple programming languages. This sort of digital polyglotism can yield a trifecta of benefits: bolstering one’s versatility in an ever-shifting tech landscape, enhancing one’s earning capacity, and setting the stage for sustained career success.


Become a versatile programmer 

Cross-training in multiple programming languages will make you a versatile programmer — one who’s able to avoid the common issue of tunnel vision. Unfortunately, programmers experienced in just one programming language typically get locked into a set way of operating. Problems and obstacles are therefore generally approached in the “one correct way”. However, it pays to remember there are multiple approaches to problem-solving in software development. Just take a look at how different the Go and JavaScript methods of error handling are: 

// Go

err := doSomethingDangerous()

if err != nil {

  fmt.Println(err)

}

Compared to: 

// JavaScript

try {

doSomethingDangerous()

} catch (err){

  console.log(err)

}

Both methods have their strengths and weaknesses depending on the situation. Go’s method, for example, works well for enterprise software development, while JavaScript is more useful for webpage rendering. Ultimately, when you cross-train in multiple languages, you’ll gain a better understanding of each one, which means you can more easily recognize the best approach for solving a problem at hand. 

Keep your skills fresh and relevant

The programming landscape is ever-evolving. An unexpected change can easily make any skill you’ve learned either outdated or, conversely, highly relevant. For example, the once-popular Apple’s Object-C has now fallen out of favour. At the same time, Fortan — the first-ever commercial programming language — recently returned after over ten years out of the spotlight. So, by limiting yourself to skills in just one language, you face a higher risk of getting left behind if that language ever declines in popularity in the future — or if your business simply decides to move in another direction and adopt a new technology you’re not already skilled in. Cross-training will put you in a better position to adapt to the industry’s changing needs as and when they happen and open you up to more opportunities. Yet, although you may realize the importance of cross-training, you may find it challenging to fit it into your busy schedule. Fortunately, eLearning is a simple and convenient way to fit your studies in. Elearning courses primarily offer the benefit of being flexible. The course content is available 24 hours a day, seven days a week — you simply log on and off again as suits your schedule. 

Boost your earning potential

“Tech workers’ salaries can grow as much as 69% as they gain more knowledge and experience”, Bankrate reports. In the case of software development, cross-training in multiple languages is a particularly effective way to boost your earning potential. Recent research into the programming language requirements of job vacancies across Fortune 500 companies determined that not even one business is looking for a new hire proficient in just one language. Rather, a total of four different languages are required on average. YouTube, for example, uses multiple languages: JavaScript on the front-end, and C, C++, Java, Go, and Python on the back-end, while MariaDB, Vites, and Bigtable are used for the database. Similarly, Amazon uses Java, JavaScript, Swift, C++, and Ruby. And, you’ll find the same goes for every other major tech company — they’re all looking for developers trained in multiple languages. So, by cross-training in multiple languages, you’ll easily make yourself a more attractive candidate to major companies and therefore increase your chances of drawing a huge paycheck.  

Sticking to learning just one programming language curbs your growth potential, and also puts you at greater risk of becoming irrelevant later down the line. Fortunately, cross-training in multiple programming languages can help you become a more versatile programmer, keep your skills fresh and relevant, and boost your earning potential all in one.

Exploring the Synergy Between Developers and User Experience

Developers spend their entire working lives around state-of-the-art technology. Not only do they use it, they create it. When the developer is also the user, it’s likely that their user experience (UX) is going to differ substantially from that of the typical target end user. This divergence can quickly grow into a gaping chasm, a wide gulf between what the end user encounters in working with the technology and what the developer intended in creating it. 

After all, the average developer’s perception of “intuitive design” may well look intimidating, frustrating, and unnecessarily complex to the end user. This is why, ultimately, a developer’s creation will live or die with the user. It’s not about how sophisticated the design is or how advanced the skill set required to build it may be. It’s about how readily your end user can master the technology, and discover, explore, and adopt the tool’s diverse functions. It’s about how your end user feels about the technology when they encounter it for the first time.

That’s why the synergy between developers and the user experience is of the utmost importance. Without this strong nexus between the two, the final product is liable to fail. Let’s examine the synergy between developers and user experience and how you can maximize it for exceptional outcomes.

Minding the Gap

One of the greatest threats to the success of any development project is the UX blind spot that can so easily emerge as developers pursue their own vision of success. This is why UX must remain top of mind at all phases of the development process. 

This requires both discipline and commitment. Integrating UX considerations at every stage inevitably means that linear development is unlikely. The good news, though, is that recursive and responsive design processes, such as those used in Agile development, can be more efficient, productive, and cost-effective. 

The key to this process, however, lies not only in frequent UX testing but also in testing the right things. As a developer, for example, you might be interested in how the end user experiences a particular function, whereas they may encounter unexpected obstacles that take precedence for them. 

Navigation tools that you’ve worked so diligently to make both intuitive and highly functional will mean nothing if you’ve not scaled the technology appropriately. Thus, while you might see only the elegant design and hours of effort expended to create it, your end user will notice only the painfully slow responsiveness. 

This means that UX testing must consider, and even prioritize, the macro view as well as the micro. If you’re soliciting only user feedback on the functionality and aesthetics of the navigation tool, in other words, you’re going to miss the critical factor that’s undermining your UX. 

Collaboration and Consensus

As we’ve seen, UX, like beauty, is often in the eye of the beholder, and that means that it’s not enough to rely only on teams of developers and designers to predict the users’ experience. You must collaborate with those outside of the team’s own technology bubble.

Interdepartmental collaboration is essential not only for understanding how your target end user is likely to experience the technology but also for determining what their technology needs are. Effective UX design, in fact, is often a function of the quality of communication between developers, stakeholders, and consumers. 

Marketers, sales reps, and customer service agents are going to have a unique perspective, for instance, not only on what kinds of innovations are needed both within and outside of the organization. They’re going to have their fingers on the pulse of the market and its evolutions because they’re on the front lines, fielding consumer complaints and responding to their requests. 

They’re also working in the trenches, meaning that they have a depth of knowledge regarding your company’s tech infrastructure that even your most experienced developers may not. After all, once you’ve handed the tools off, you are likely to have comparatively little experience with the technologies that they deploy every day. 

Thus, if you want to optimize your UX design process, then you must optimize your capacity to collaborate with colleagues and partners organization-wide. It’s imperative to implement the best collaboration tools, ones that will bring together not only onsite employees but also remote workers, stakeholders, and clients. This will ensure that the feedback you receive on the needs, expectations, and experiences of your target end users will be timely, relevant, and comprehensive.

The Takeaway

Technology isn’t created in a vacuum. It’s made for a specific purpose and to serve a designated target user. But unless and until you tap into that all-important synergy between development and user experience, your technology will simply never be all that it could and should be.

Building a video conferencing app with Agora and React

Developing real-time engagement applications where users interact with each other using live audio, video, and text is a really complex challenge. It requires a lot of time and effort to build out the infrastructure and logic to support these features. The biggest challenge is to have your infrastructure be reliable, scalable, and low latency to deliver the best user experience.

At Agora, we’re solving this problem for developers at scale. Agora’s Software-Defined Real-Time Network™ provides the broadest range of coverage throughout the world (200+ countries), while delivering high-quality with ultra-low latency (400ms or less). To make leveraging the Agora platform easy for developers we offer easy to use SDKs for Android, iOS/macOS, Windows, Web, Electron, Flutter, React Native, Unity and more. With our SDKs you can build and deploy your real-time engagement application in a matter of hours instead of days.

Getting back to the topic for this blog, how does one build a video conferencing app with Agora and React? Agora recently announced a new beta SDK for React. We’ll look at how it works with a simple demo app.

Getting Started

Creating an Account with Agora

  • Sign up for an account and log in to the Agora Console.
  • Navigate to the Project List tab under the Project Management tab
  • Create a project by clicking the blue “Create” button.
  • When prompted to use App ID + Certificate, select App ID only.
  • Retrieve the App ID, which will be used to authorize your requests while you’re developing the application.

Note: This blog does not implement token authentication, which is recommended for all RTE apps running in production environments. For more information about token-based authentication in the Agora platform, see this guide.

Setting up a React Project

The source for this project is available on GitHub, you can also try out a live demo.
To follow along, scaffold a React project using Vite:

  1. Ensure that you have installed Node.js LTS and NPM.
  2. Open a terminal and execute npm create vite@latest agora-videocall — — template react-ts
  3. This creates a folder named “agora-videocall”
  4. Navigate to the project: cd agora-videocall
  5. Install the dependencies: npm i agora-rtc-react agora-rtc-sdk-ng
  6. You can start a dev server by running npm run dev

Time to Code

We’ll start in the App.tsx file. Since this demo is going to be really simple, we’ll create all our components in the same file. Let’s start by importing the dependencies we’ll use in our application.

import { useState } from "react";
import { AgoraRTCProvider, useJoin, useLocalCameraTrack, useLocalMicrophoneTrack, usePublish, useRTCClient, useRemoteAudioTracks, useRemoteUsers, RemoteUser, LocalVideoTrack } from "agora-rtc-react";
import AgoraRTC from "agora-rtc-sdk-ng";
import "./App.css";

The Agora React SDK provides a set of hooks and components to manage the state of your application and to render the video call interface.
In our App, let’s initialize a client object from the Agora SDK and pass it to the useRTCClient hook. The client object represents the local user in the video call. Passing the object to the useRTCClient hook makes it available to the rest of the application (and hooks) by using a React Provider. We’ll add this in a bit, first, let’s set up our application state:

const App = () => {
  const client = useRTCClient(AgoraRTC.createClient({ codec: "vp8", mode: "rtc" }));
  const [channelName, setChannelName] = useState("test");
  const [AppID, setAppID] = useState("");
  const [token, setToken] = useState(null);
  const [inCall, setInCall] = useState(false);
  • channelName: Represents the name of the channel where users can join to chat with one another. Let’s call our channel “test”.
  • AppID: Holds the Agora App ID that we obtained before from the Agora Console. Replace the empty string with your App ID.
  • token: If you’re using tokens, you can provide one here. But for this demo we’ll just set it as null.
  • inCall: A Boolean state variable to track whether the user is currently in a video call or not.

Next, we display the App component. In the return block, we’ll render an h1 element to display our heading. Now, based on the inCall state variable, we’ll display either a Form component to get details (App ID, channel name, and token) from the user or display the video call:

return (
    <div style={styles.container}>
      <h1>Agora React Videocall</h1>
      {!inCall ? (
        <Form
          AppID={AppID}
          setAppID={setAppID}
          channelName={channelName}
          setChannelName={setChannelName}
          token={token}
          setToken={setToken}
          setInCall={setInCall}
        />
      ) : (
        {/* Videocall here */}
      )}
    </div>
  );
};

To create the video call component, let’s first wrap it with the AgoraRTCProvider component, this accepts a client returned from the useRTCClient hook and makes it accessible down the tree. You should add this at the top level of your video call.
We’ll create a <Videos> component next, to hold the users’ videos, passing it our props from before. We’ll also display an End Call button that ends the call by setting the inCall state to false:

return (
    <div style={styles.container}>
      <h1>Agora React Videocall</h1>
      {!inCall ? (
        <Form
          AppID={AppID}
          setAppID={setAppID}
          channelName={channelName}
          setChannelName={setChannelName}
          token={token}
          setToken={setToken}
          setInCall={setInCall}
        />
      ) : (
        <AgoraRTCProvider client={client}>
          <Videos channelName={channelName} AppID={AppID} token={token} />
          <button onClick={() => setInCall(false)}>End Call</button>
        </AgoraRTCProvider>
      )}
    </div>
  );
}

export default App;

Video Component

We destructure the props to access the AppID, channelName and token.
The Agora React SDK also gives you useLocalMicrophoneTrack and useLocalCameraTrack hooks, these create and set up the local microphone and camera tracks respectively. Since the process to create these tracks is asynchronous they also give you a loading and an error state along with the tracks.

function Videos(props: { channelName: string; AppID: string; token: string }) {
  const { AppID, channelName, token } = props;
  const { isLoading: isLoadingMic, localMicrophoneTrack } = useLocalMicrophoneTrack();
  const { isLoading: isLoadingCam, localCameraTrack } = useLocalCameraTrack();

We can use the useRemoteUsers hook to access the other (remote) users that join our video call. This hook gives you an array of objects, each object represents remote users in the call. The array is like your React state that gets updated each time someone joins or leaves the channel, we’ll use this to render our UI and keep it in sync with the form of the call:

 const remoteUsers = useRemoteUsers();

We can use the usePublish hook to publish the local microphone and camera tracks. You can pass in an array of tracks you want to publish to the channel, these tracks can be subscribed and viewed by other users who join the same channel.

 usePublish([localMicrophoneTrack, localCameraTrack]);

To start the call we need to join a room or a channel. We can do that by calling the useJoin hook and passing in the AppID, channelName, and token as props.

useJoin({
    appid: AppID,
    channel: channelName,
    token: token === "" ? null : token,
  });

We can access the remote users’ audio tracks with the useRemoteAudioTracks hook by providing it the remoteUsers array. This hook automatically handles subscribing and unsubscribing to the user tracks as your component is mounted and tracks are available.

const { audioTracks } = useRemoteAudioTracks(remoteUsers);

To listen to the remote users’ tracks, we can map over the audioTracks array and call the play method for each available track:

 audioTracks.map((track) => track.play());

We’ll check if either the microphone or the camera is still loading and render a simple loading message:

const deviceLoading = isLoadingMic || isLoadingCam;
  if (deviceLoading) return <div style={styles.grid}>Loading devices...</div>;

Once the tracks are ready, we can render a grid with videos of all the users in the channel. We can render the user’s own (local) video track using the LocalVideoTrack component from the SDK, passing it the localCameraTrack as the track prop:

return (
    <div style={{ ...styles.grid, ...returnGrid(remoteUsers) }}>
      <LocalVideoTrack track={localCameraTrack} play={true} style={styles.gridCell} />
      {/* Remote videos here */}
    </div>
  );
}

We can display the remote users’ video tracks using the RemoteUser component. We’ll iterate through the remoteUsers array, passing each user as a prop to it:

return (
    <div style={{ ...styles.grid, ...returnGrid(remoteUsers) }}>
      <LocalVideoTrack track={localCameraTrack} play={true} style={styles.gridCell} />
      {remoteUsers.map((user) => (
        <RemoteUser user={user} style={styles.gridCell} />
      ))}
    </div>
  );
}

These components are unopinionated so you can style them as you like.

That’s all the code we need to build a video conferencing app with Agora and React. Here’s what the final code looks like:

function Videos(props: { channelName: string; AppID: string; token: string }) {
  const { AppID, channelName, token } = props;
  const { isLoading: isLoadingMic, localMicrophoneTrack } = useLocalMicrophoneTrack();
  const { isLoading: isLoadingCam, localCameraTrack } = useLocalCameraTrack();
  const remoteUsers = useRemoteUsers();
  const { audioTracks } = useRemoteAudioTracks(remoteUsers);

  usePublish([localMicrophoneTrack, localCameraTrack]);
  useJoin({
    appid: AppID,
    channel: channelName,
    token: token === "" ? null : token,
  });

  audioTracks.map((track) => track.play());
  const deviceLoading = isLoadingMic || isLoadingCam;
  if (deviceLoading) return <div style={styles.grid}>Loading devices...</div>;

  return (
    <div style={{ ...styles.grid, ...returnGrid(remoteUsers) }}>
      <LocalVideoTrack track={localCameraTrack} play={true} style={styles.gridCell} />
      {remoteUsers.map((user) => (
        <RemoteUser user={user} style={styles.gridCell} />
      ))}
    </div>
  );
}

Form and styling

For the sake of completeness, here’s what the Form component looks like:

function Form(props) {
  const { AppID, setAppID, channelName, setChannelName, token, setToken, setInCall } = props;
  return (
    <div>
      <p>Please enter your Agora AppID and Channel Name</p>
      <label htmlFor="appid">Agora App ID: </label>
      <input id="appid" type="text" value={AppID} onChange={(e) => setAppID(e.target.value)} placeholder="required"/>
      <br /><br />
      <label htmlFor="channel">Channel Name: </label>
      <input id="channel" type="text" value={channelName} onChange={(e) => setChannelName(e.target.value)} placeholder="required" />
      <br /><br />
      <label htmlFor="token">Channel Token: </label>
      <input id="token" type="text" value={token} onChange={(e) => setToken(e.target.value)} placeholder="optional" />
      <br /><br />
      <button onClick={() => AppID && channelName ? setInCall(true) : alert("Please enter Agora App ID and Channel Name")}>
        Join
      </button>
    </div>
  );
}

Conclusion

That’s all it takes to put together a high-quality video conferencing app with the Agora React SDK. We’ve barely scratched the surface in terms of what’s possible. You can add a ton of features like virtual backgrounds, selective subscriptions, waiting rooms and so on. Learn more by visiting the docs and our API reference.

We’re looking for feedback on how we can improve the SDK in this beta period. Please contribute by opening issues (and submitting PRs) on our GitHub repo.
